Description
技术领域
本发明涉及一种印刷技术领域,具体地说是一种光影3D转印技术。
背景技术
在不同立体产品上转印各种不同效果的仿真图案或艺术个性化图案,传统的工艺,如水转印、丝印、热转印等,都有局限性,生产效率低和工艺较为繁杂低效。
发明内容
本发明提供一种光影3D转印技术,其目的是解决现有技术的缺点,提高生产效率。
本发明解决其技术问题所采用的技术方案是:
一种光影3D转印技术,其特征在于:包括如下步骤:
步骤1:
在产品表面喷涂油漆,进行烘干,油漆干透且附着在产品表面;
步骤2:
把产品放入暗房的水池或隧道式水槽,水池或隧道式水槽里装入卤化银感光剂,产品在暗房里浸泡感光剂30秒,提起,让剩余感光剂留在水池或水槽,产品移开在暗房里晒干或烘干,放在指定位置上;
步骤3:
在电脑上设计好要转印的图案或照片的内容且编排好产品的转印位置,通过曝光灯,把图片信息通过不同的色彩强度在产品进行光合反应,使产品表面产生潜影;
步骤4:
通过曝光后的产品,移到另一个水池或水槽,通过喷显影液,产品表面显像出所要的各种图像;
步骤5:把产品移出,放入装有定影剂的水池或水槽,浸泡15秒取出;
步骤6:取出产品烘干,喷涂保护层。
步骤1中,根据产品的材质不同,选择对应的油漆如下:
a.金属材质,选用丙烯酸或环氧树脂类;
b.塑胶类材质,选用PU漆;
c.木质类材质,选用木器漆;
d.树脂类材质,选用PU漆。
步骤2中,感光剂为在凝胶中加入氧溴化银。
步骤4中,显影液的显影剂选择米吐尔或对苯二酚或菲尼酮。
步骤5中,定影剂为硫代硫酸钠。
步骤6中,保护层为面漆或明胶。
本发明的有益之处在于:
本专利可以选择较大的暗室,可以尽可能放更多的产品,所以可以在巨大空间中大量转印出各种各样的个性化的外观效果;利用曝光技术曝光时间是一瞬间,因此几秒钟就可转印出非常多的产品;转印的效果非常好,通过图片、相片或其他制作,不需开版,不受颜色的限制,所以图像颜色不受限制;可以通过光线曝光达到把照片的图像转印在指定的位置上,且不受表面凹凸立体的影响,产品的任何部位都可以选择性的转印。
具体实施方式
本发明包括如下步骤:
步骤1:
在不同材质的产品表面,首先根据材质不同(如金属、塑料、有机复合材料等)喷涂对应附着力好的油漆(底漆),可以是油漆涂料或水性涂料,进行烘干,油漆干透且附着在产品表面;
根据产品的材质不同,选择对应的油漆如下:
a.金属材质,选用烤漆,如丙烯酸、环氧树脂类;
b.塑胶类材质,PC、PP、ABS尼龙等,选用PU漆,以双组份油漆优选;
c.木质类材质,选用木器漆,如硝光漆、PU漆、丙烯酸树脂等;
d.树脂类材质,选用PU漆;
步骤2:
把产品放入输送线上(或手提)进入一个暗房(没有光线)的水池或隧道式水槽,水池或隧道式水槽里装入卤化银感光剂,产品在暗房里浸泡感光剂30秒左右,提起,让剩余感光剂留在水池或水槽,产品移开在暗房里晒干或烘干,放在指定位置上;
感光剂可以选择在凝胶中加入氧溴化银;
步骤3:
在电脑上设计好要转印的图案或照片的内容且编排好产品的转印位置,通过曝光灯,把图片信息通过不同的色彩强度在产品进行光合反应,使产品表面产生潜影,感光剂是具有感光作用的卤化银微小晶体,在光线照射下发生潜在的光化学变化,形成了人的肉眼无法观察到的影像也即潜影;
步骤4:
通过曝光后的产品,移到另一个水池或水槽,通过喷显影液,起到化学分解和还原作用,产品表面显像出所要的各种图像;
显影剂:是显影液的重要组成部分,起到化学分解和还原的作用,可以选择米吐尔、对苯二酚、菲尼酮等;
米吐尔(软性显影剂):是一种白色或略带灰褐色的小结晶体。能溶于水,但溶解缓慢,在亚硫酸钠(较浓)溶液中溶解度较小不溶解。
配制方法:配制时,放入较少无水亚硫酸钠,把水中的氧中和掉,再放入其他药液。
放入药液的先后顺序:显影剂、保护剂、促进剂、抑制剂。
特性:软性显影剂,急性显影剂,显影能力强,速度快,显影时对影像的明暗两大部分同时显影。反差小,柔和细腻,受温度影响小。在弱酸性溶液中也有显影能力,受PH值影响不大。
对苯二酚:是一种白色细小针状结晶体,易溶于水和亚硫酸钠的溶液中,具有还原性(体现在保存时间长,又回到结晶)。
它属于慢性显影剂,主要功能是银盐密度增加。开显影能力缓慢,虽时间越长速度越快,对暗部显影能力小,对强光部分显影能力强(银盐堆积多而厚),所以反差大。主要用于提高反差。在温度低于(14-15度)的情况下海得尔显影能力丧失。
在常用配方中与米吐尔配合使用效果好,能使影像柔和而且层次丰富。
菲尼酮:白色结晶体,它溶解度受温度影响,温度高易溶,性能与米吐尔相近,比米吐尔更加柔和细腻,单独使用,显影能力小,通常与对苯二酚同使用。
优点:用量少,损耗低,不易被氧化。
步骤5:把产品移出,放入装有定影剂的水池或水槽,浸泡15秒取出;
定影剂:硫代硫酸钠(大苏打,海波)
性能:是一种无色棱状晶体,易溶于水。可以将乳剂中卤化银完全溶解掉,而是以曝光的银粒固定留在片基上。硫酸钠是最理想的定影剂,定影液中含量为25%是定影能力最强,回到不能超过40%,50%是定影能力降为5%。海波之所以能够定影,主要是它和卤化银反应生成稳定的可溶性络盐。
步骤6:取出产品烘干,喷涂保护层(可以是面漆或明胶),使产品的效果层不容易和刮伤或损坏。
本说明书中各个实施例采用递进的方式描述,每个实施例重点说明的都是与其他实施例的不同之处,各个实施例之间相同相似部分互相参见即可。对所公开的实施例的上述说明,使本领域专业技术人员能够实现或使用本发明。对这些实施例的多种修改对本领域的专业技术人员来说将是显而易见的,本文中所定义的一般原理可以在不脱离本发明的精神或范围的情况下,在其它实施例中实现。因此,本发明将不会被限制于本文所示的这些实施例,而是要符合与本文所公开的原理和新颖特点相一致的最宽的范围。
